I've queued it immediately after Thomas' patch. I'll let the two of you tell me if it's better to squash them together to avoid breaking bisect and mark you co-authors. Willy

Squashing them sounds like the correct solution to me. Thomas

OK I've done it for now in my branch. I'm going to push it as 20230604-nolibc-rv32+stkp6. All tests pass fine again for me now on all supported archs. I'll pass this one to Paul, I think it's fine for 6.5. I just don't know if he still has tests planned on his side for 6.5 (Paul always re-runs the whole tests after integration and often spots failures). By the way, I'm still using my test-all script that's extremely convenient to test the expected results from user-mode (it basically does what run-user does, but for all archs and at -O0, -Os, -O3). I'm sharing it attached since I think it can help you and Zhangjin in your respective tests. That's how I'm cheating to spot build issues in contributed changes. I have not committed it because it's ugly and I don't know where to put it, but I think you'll find it convenient nevertheless. I'm starting it like this: $ ./test-all-opts.sh | tee test16.out $ grep passed test16.out 136 test(s) passed, 2 skipped, 0 failed. See all results in run-arm64.out 135 test(s) passed, 3 skipped, 0 failed. See all results in run-arm-march=armv5t_-marm.out 135 test(s) passed, 3 skipped, 0 failed. See all results in run-arm-march=armv5t_-mthumb.out 135 test(s) passed, 3 skipped, 0 failed. See all results in run-arm-march=armv7-a_-marm.out 135 test(s) passed, 3 skipped, 0 failed. See all results in run-arm-march=armv7-a_-mthumb.out 136 test(s) passed, 2 skipped, 0 failed. See all results in run-i386.out 136 test(s) passed, 2 skipped, 0 failed. See all results in run-i386-march=i586.out (...) $ grep ' [^0] failed' test16.out || echo OK OK Hoping this helps, Willy

Commit a89c937d781a ("tools/nolibc: support nanoseconds in stat()") added nanoseconds for stat() but missed the statx case, this adds it. The stx_atime, stx_mtime, stx_ctime are in type of 'struct statx_timestamp', which is incompatible with 'struct timespec', should convert explicitly. /* include/uapi/linux/stat.h */ struct statx_timestamp { __s64 tv_sec; __u32 tv_nsec; __s32 __reserved; }; /* include/uapi/linux/time.h */ struct timespec { __kernel_old_time_t tv_sec; /* seconds */ long tv_nsec; /* nanoseconds */ }; Without this patch, the stat_timestamps test case would fail when __NR_statx defined.
